RockShox BoXXer Ultimate Charger3 200 20TAx110 - Electric Red With the BoXXer Ultimate, RockShox is launching a fork that is built for one purpose: winning races. A 38 mm chassis paired with the updated DebonAir+ TwinTube spring, SKF Low Friction wipers and the ButterCups offer you a completely new driving experience that you otherwise only know from a steel spring. The CNC-milled and anodized crown not only looks outrageously good, it also saves weight, is stable and implements every movement you make on the handlebars directly. The smallest bumps and vibrations are eliminated by up to 20% thanks to the ButterCups, and yet your fork is always high enough in the spring travel to offer you sufficient safety and reserves even on the steepest part of the route. But since looks and springs aren't everything a fork needs to be able to do, the Charger 3 comes into play. Specially tailored to the requirements of gravity sports, it ensures that you always have everything under control, no matter how rough the situation. Thanks to the precisely adjustable low and high-speed compression and the adjustable low-speed rebound, you are guaranteed to find the perfect setup for your needs. Or to put it very simply, the BoXXer Ultimate takes you straight to the top step of the podium. 38mm chassis Thanks to the 38 mm chassis, the fork has a good balance of stiffness and comfort. CNC crown Lightweight, milled and anodized crown for premium looks and durability. The scope of delivery includes a short and a high crown to cover all head tube lengths. Maxle Stealth 20x110mm Very light thru-axle, which can be mounted and removed with a 6 mm Allen key. In addition to a clean look, it also saves some weight on the unsprung mass. DebonAir+ Double-tube air springs specially developed for the BoXXer, which strike a perfect balance between sensitivity to small bumps and optimal support over the entire spring travel. Charger 3 RC2 The Charger 3 RC2 is perfectly matched to the BoXXer with its DebonAir+ air spring and ButterCups. The damping design enables precise adjustment of the high and low speed compression as well as the low speed rebound. The Maxima Plush Damping Fluid reduces friction within the cushioning and lets you glide smoothly over all bumps. Buttercups ButterCups filter 20% of high frequency vibrations. This significantly reduces hand and arm fatigue, allowing you to feel fresher for longer and have more control. Bottomless tokens Here you can easily vary the air volume of your fork with optionally available tokens (volume spacers) and thus adapt the spring characteristic to your riding style. SKF Ultra Low Friction Seals The extremely low-friction wiper seals ensure long-lasting fork performance and a low breakaway torque. Maxima Plush Damping Fluid The best suspension needs the best oil. Maxima Plush is designed to reduce suspension wear, friction and noise. Maxima Plush Dynamic Suspension Lube Reduced friction with long service life makes this lubricant the choice of SRAM engineers.
